The Colorado Department of Revenue implemented RightNow Technologies to provide taxpayers with self-service access to tax information online in order to reduce call volumes and improve customer service. This resulted in an ROI of 8,732% and payback period of just 3 days. Key benefits included avoiding costs of hiring additional staff for the call center during peak tax season, and providing more rapid, accurate and consistent responses to taxpayers' questions. Continuous refinement of the knowledge base based on analytics of taxpayer interactions further optimized the system.
